I got honorably discharged from the Army for failure to lose weight on 3 consecutive weigh ins. I was 5'10" and 203 lbs. Basically any weigh in where I had lost weight since the previous weigh in reset the counter. If I was on a standard base I could have done it. I lost over 30 lbs. during basic and AIT. I was stationed on a tiny base with no mess hall, a tiny kitchen nobody ever used and no knowledge of cooking or nutrition. So it was basically always eating out.
I see a real challenge at 100 pounds in 9 months. As compared to the other "challenge " out there I see this as a betting opportunity regardless of starting weight. Yea going from 500 to 600 is easier than 200 to 300 it's still the same concept. Only difference is rules need to be set from the start with updates at predetermined dates.
Why not hide all the nonsense about caring about the "contestant" and make it all about the sport of it. Who is stepping up to take the cash?
